Ricoh sues Quanta Storage and Asustek for disc patent infringement

From the Web, 28th August 2006

Japan-based Ricoh on August 24 filed legal proceedings at a US District Court in Wisconsin against Quanta Storage and Asustek Computer, two leading makers of optical disc drives (ODDs) in Taiwan, for infringing on four of its patents related to CD-RW and DVD+RW formats, according to industry sources in Taiwan. In response, both Quanta Storage and Asustek indicated they have not received notification about the lawsuit and therefore could not make an assessment.
